Answer:
B is the correct option
Explanation:
K= the ratio of product of concentration of products to the product of concentration of reactants raised to power equal to their cofficients.
Density can be calculated using the following rule:
density = mass / volume
therefore,
mass = density x volume
From the givens:
we have the density = 1030 kg/m^3 and volume = 1.89 m^3
Substitute in the equation to get the mass as follows:
mass = 1030 x 1.89 = 1.9467 x 10^3 kg
Approximately 99 because there is the same amount of electrons and the only things that go into the nucleus is protons and neutrons.
Answer:
The only balanced equation is:
2KClO₃ → 2KCl + 3O₂
Explanation:
In reactant side: 6 atoms of O, 2 atoms of Cl and 2 atoms of K
In product side: 2 atoms of K and 2 atoms of Cl + 6 atoms of O
CO + 3H₂ → CH₃OH
In reactant side: 1 C, 1 O and 6 H
In product side: 1 C, 4 H and 1 O
PCl₃ + 2Cl₂ → PCl₅
In reactant side: 1 P, 7 Cl
In product side. 1 P, 5 Cl
Mg + N₂ → Mg₃N₂
In reactant side 1 Mg and 2 N
In product side 3 Mg and 2 N
Answer:
it should be 3
Explanation:
because its already above the 4th line so it wouldn't make sense to say 2 4/4
